Maximum field enhancements E s-max . The maximum field enhancements E s-max outside the Au shell of the Au-silica-Au multilayer nanoshells (black dots) and NSNE (red dots) at different resonant wavelengths of \( {\left|{\omega}_{-}^{-}\right\rangle}_1 \) modes. Inset: dependence of the resonant wavelength of \( {\left|{\omega}_{-}^{-}\right\rangle}_1 \) modes on the Au core radius r 1 in the Au-silica-Au multilayer nanoshells (black squares) and NSNE (red squares).
